Answer:

Step-by-step explanation:

Create a proportion

$\frac{x}{12} = \frac{63}{84}$

84 divide by what gives you 12? 7

So divide 63 by 7, and you get 9.

This doesn't work with all of these problems so you can always cross multiply then divide.

12(63) = 756

84(x) = 84x

84x = 756

84x/84 = 756/84

x = 9

The probability is 0.1667.

. A square picture frame occupies an area of 112 ft2 . What is the length of each side of the picture in simplified radical form

saw5 [17]

Recall that a square is just a rectangle with all sides equal.

and the area of a rectangle is just length * width.

$\bf \textit{area of a rectangle}\\\\
A=length\cdot width\quad 
\begin{cases}
length=x\\
width=x\\
A=112
\end{cases}\implies 112=x\cdot x\implies 112=x^2
\\\\\\
\sqrt{112}=x\implies \sqrt{16\cdot 7}=x\implies \sqrt{4^2\cdot 7}=x\implies 4\sqrt{7}=x$
